The minutes will work until bradley comes back. And just like Doc said , when bradley comes back we will see. Every year we have too much depth , and injuries take away all of it.
Now to answer your question I could see the minutes like this:
PG: Rondo 35, Terry 13
SG: Bradley 22, Lee 16, Terry 10
SF: Pierce 30, Green 12, Lee 6
PF: Bass 26, Green 16, Wilcox 6
C: Garnett 30, Wilcox 18
U could take a bit from Wilcox and Bass and give the minutes to Sullinger or Milicic, but you kinda get the idea !
